Purpose: this product USES high pressure polyinsulation with small interface constant.
矿用信号电缆是一种信号传输工具。一般信号电缆传输的信号很小,为了避免信号受到干扰,信号电缆外面有一层屏蔽层,包裹的导体的屏蔽层,一般为导电布,编织铜网或铜泊(铝),屏蔽层需要接地,外来的干扰信号可被该层导入大地,避免干扰信号进入内层导体干扰降低传输信号的损耗。

In order to evaluate the flame-retardant performance of wire cables, iec 60332-1, iec 60332-2 and iec 60332-3 were formulated respectively. Iec60332-1 and iec60332-2 are respectively used to evaluate the flame retardant capability of a single cable when it is laid on an incline and vertically (corresponding to GB12666.3 and GB12666.4 in China). Iec60332-3 (domestic e to gb) is used to evaluate the flame retardant capability of beam cable when it is vertical, compared with that of beam cable when it is vertical.

在室外装修中,要根据施工图中规定的涂料来施工,但有的施工图中仅注明墙面刷外墙涂料,而未注明品种时,就要根据具体情况来选择适当的外墙涂料。按建筑装修部位确定在客流量较大的场所(如大厅、餐厅(餐厅装修效果图)和走廊(走廊装修效果图)等墙面),应选用具有良好的耐老化、耐污染、耐水、保色性好和附着性较强的涂料。在客流量较少的场所,应选用具有防火、防霉、防沾污和易刷洗性好的涂料。在湿度较大的场所(如浴室、厕所和厨房(厨房装修效果图)等),应选用具有耐水、防火、防霉、防沾污、易刷洗等性能的涂料。
